NAME
Paws::Firehose::ParquetSerDe
USAGE
This class represents one of two things:
Arguments in a call to a service
Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.
As an example, if Att1 is expected to be a Paws::Firehose::ParquetSerDe object:
$service_obj->Method(Att1 => { BlockSizeBytes => $value, ..., WriterVersion => $value });Results returned from an API call
Use accessors for each attribute. If Att1 is expected to be an Paws::Firehose::ParquetSerDe object:
$result = $service_obj->Method(...);
$result->Att1->BlockSizeBytesDESCRIPTION
A serializer to use for converting data to the Parquet format before storing it in Amazon S3. For more information, see Apache Parquet (https://parquet.apache.org/documentation/latest/).
ATTRIBUTES
BlockSizeBytes => Int
The Hadoop Distributed File System (HDFS) block size. This is useful if you intend to copy the data from Amazon S3 to HDFS before querying. The default is 256 MiB and the minimum is 64 MiB. Kinesis Data Firehose uses this value for padding calculations.
Compression => Str
The compression code to use over data blocks. The possible values are UNCOMPRESSED, SNAPPY, and GZIP, with the default being SNAPPY. Use SNAPPY for higher decompression speed. Use GZIP if the compression ratio is more important than speed.
EnableDictionaryCompression => Bool
Indicates whether to enable dictionary compression.
MaxPaddingBytes => Int
The maximum amount of padding to apply. This is useful if you intend to copy the data from Amazon S3 to HDFS before querying. The default is 0.
PageSizeBytes => Int
The Parquet page size. Column chunks are divided into pages. A page is conceptually an indivisible unit (in terms of compression and encoding). The minimum value is 64 KiB and the default is 1 MiB.
WriterVersion => Str
Indicates the version of row format to output. The possible values are V1 and V2. The default is V1.
